It could be related to the limitations of the ARM processor on the E100. I haven't tried the OFDM examples. The workarounds at this point seem to be: help implement some of the ARM NEON optimizations in Volk to squeeze out more performance or switch back to an USRP running on a system capable of handling higher bandwidths, e.g., your USRP1 with (most likely) an Intel processor.

Subject: OFDM on E100
Have you ever tried the ofdm examples in gr-digital on E100?
I got a lot of 'U' underrun and only observed DC output on another receiver.
The example works on USRP1. So is it just a hardware limitation on E100?
Do you have any workaround solution?
